[FIXED] How to solve (at com.fasterxml.jackson.databind) error

September 01, 2022 hibernate, jackson, java, spring-boot

Issue

I got these error message while trying to send request(POST) through postman. It seems that the problem is because of the lazy initialization for Hibernate and I've searched some solution but it doesn't work.

Below is my entity class.

@Entity
@Table(name = "`ORDER`")
public class OrderVO implements Serializable{
    private static final long serialVersionUID = 1L;

@Id
@Column(name = "ORDER_ID")
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Integer orderId;

@Column(name = "USER_ID")
private Integer userId;

@Column(name = "ORDER_STATUS", insertable = false)
private Integer orderStatus;

@Column(name = "NOTE")
private String note;

@Column(name = "USER_LOCATION")
private String userLocation;

@Column(name = "ORDER_CREATE", insertable = false)
private Timestamp orderCreate;

@Column(name = "ORDER_DONE", insertable = false)
private Timestamp orderDone;

@Column(name = "PRODUCT_KCAL_TOTAL")
private Integer productKcalTotal;

@Column(name = "TOTAL")
private Integer total;

@Column(name = "DEL_COST")
private Integer delCost;

@Column(name = "USE_CASH")
private Boolean useCash;

@Column(name = "CREDIT_ID")
private String creditId;

@Column(name = "DISCOUNT")
private Integer discount;

@Column(name = "RATING", insertable = false)
private Boolean rating;

@Column(name = "RES_RATE", nullable = true)
private Double resRate;

@Column(name = "DEL_RATE", nullable = true)
private Double delRate;

@Column(name = "RES_COMMENT", nullable = true)
private String resComment;

@Column(name = "DEL_COMMENT", nullable = true)
private String delComment;

@Column(name = "PROMOTE_ID", nullable = true)
private Integer promoteId;

@OneToMany(
        mappedBy = "orderVO",
        cascade = {CascadeType.REMOVE} 
)
private Set<OrderDetailVO> orderDetailVO;

@ManyToOne
@JoinColumn(
        name = "RES_ID",
        referencedColumnName = "RES_ID"
)
private ResVO resVO;

@ManyToOne
@JoinColumn(
        name = "DEL_ID",
        referencedColumnName = "DEL_ID"
)
private DelBean del;

Service:

@Service
@Transactional
public class OrderServiceImpl implements OrderService {
    
    @Autowired
    private OrderDAO dao;
    @Autowired
    private PromoteListDAO promoteListDAO;
    
        
    @Override
    public List<OrderVO> adminFindOrderAll(){
        List<OrderVO> list = dao.getAll();
        return list;
    }

Repository:

    @Repository
    public class OrderDAOimpl implements OrderDAO {

    @PersistenceContext
    private Session session;
    
    public Session getSession() {
        return session;
    }


    @Override
    public List<OrderVO> getAll() {
        return (List<OrderVO>) this.getSession().createQuery("FROM OrderVO ORDER BY orderId", 
        OrderVO.class).list();
    }

Controller:

    @RestController
@RequestMapping(path = {"/AdminOrderAllServlet"})
public class AdminOrderAllServlet{
    
    @Autowired
    private OrderService orderService;
    
    @PostMapping
    public Map<String, Object> handlerMethod() {
        Map<String, Object> respObj = new HashMap<String, Object>();
        List<OrderVO> list = orderService.adminFindOrderAll();
        respObj.put("Orders", list);
        return respObj;
    }
    
}

One of the solution is to turn off lazy in application.properties but it still doesn't work.

jpa: properties.hibernate: enable_lazy_load_no_trans: true

Please let me know if any ideas, thanks!

Solution

You need to use @JsonManagedReference and @JsonBackReference to allow Jackson to better handle the relationship.

Here down is example

public class A
{
    ...
    ...
    @JsonManagedReference
    @OneToMany(...)
    public Set<B> b
    ...
    ...
}

public class B
{
    ...
    ...
    ...
    @JsonBackReference
    @ManyToOne(...)
    @JoinColumn(...)
    public A a
    ...
    ...
}
